=> R0 = 5, 6 or 7
R2 = buffer
<= R0, R2 preserved
C flag corrupted
These calls read information on the temporary filing system (normally the current) to the buffer pointed to by R2.
If R0 = 5 :
<name length byte><disc name><boot option byte>
of disc containing the current directory
If R0 = 6 :
<0><name length byte><current directory name><priviliged byte>
of the currently selected directory. The priviliged byte is either &00 ie allowance to create or delete objects in the directory &FF ie prohibition of creating or deleting objects; in ADFS or other FileCore based systems, you always got &00
If R0 = 7 :
<0><name length byte><library directory name><priviliged byte>
of the library directory
The names are stored without termination byte.
